Case Type   : 导入导出、备份恢复工具支持M*兼容性
Case Name   : gs_dump工具导出兼容M*列属性含on update current_timestamp
Create At   : 2023.05.04
Owner       : z@wan005
Description :
    1.创建兼容b库
    2.兼容b库下建表
    3.使用gs_dump工具导出表为纯文本格式
    4.导入之前导出的数据到新库
    5.连接导入库查询表
    6.验证on update current_timestamp属性生效
    7.清理环境
Expect      :
    1.成功
    2.成功
    3.成功
    4.成功
    5.成功，导入表的列属性on update current_timestamp成功
    6.成功,c3列自动更新为当前时间
    7.成功
